Assume two charged particles and

B

are separated by a distance of

r_{1} .

From the options below, choose the one that would result in the largest positive change in internal energy.

If A has a charge of

+ 1

and

B

has a charge of

- 2

while

r_{2}

is increased to

1.5 r_{1} .

If A has a charge of

+ 1

and

B

has a charge of

+ 1

while

r_{2}

is decreased to

0.25 r_{1} .

If A has a charge of

+ 2

and

B

has a charge of

+ 2

while

r_{2}

is decreased to

0.5 r_{1} .

If A has a charge of

+ 1

and

B

has a charge of

- 1

while

r_{2}

is increased to

2.5 r_{1} .
